Could someone in the know tell use whether or not OS9 (specifically, Coco Level 1) actually reads and verifies that the floppy disk head is on the track supposedly stepped to, before doing the real read or write? Or does the driver just figure "I want track 10, I was on track 23 so I'll just give it 13 reverse pulses and write the sector"? I'm getting some weird head motions and wonder if these could be re-seeks due to landing on the wrong track. Thanks, mike k PS: I'm using DP Johnson's SDISK, not the crippled RS CCDISK.
